Hi everyone, the problem is fixed.
We did everything...started with baking soda and vinegar and hot water, bought one of those things I posted at WalMart, used a hose, used a hanger type thingy, and warning.....we put in RidX.
The gauge may have been off. Nothing noticeable came out but since it happened right after we used our Panda (washing machine) I think there was lint somewhere. So all is well. This unit is just a little over a year old but we are planning on trading up in two years. Can't wait to have a real washer and dryer and maybe maybe fewer problems.
THANK YOU
